Source: R/map_points.R
map_points.Rd

Creates an interactive map for a data.frame containing point coordinates, optionally colored by a selected variable.

Usage

map_points(
  data,
  value = NULL,
  lon = "lon",
  lat = "lat",
  crs = 4326,
  at = NULL,
  layer_name = NULL,
  ...,
  basemaps = c("Esri.WorldGrayCanvas", "OpenStreetMap", "Esri.WorldImagery")
)

Arguments

data

A data.frame containing columns for longitude and latitude.

value

A string giving the name of the column in data to be visualized. If NULL, points are mapped without a color variable.

lon

A string with the name of the column containing longitude values. Default is "lon".

lat

A string with the name of the column containing latitude values. Default is "lat".

crs

Integer; EPSG code for the coordinate reference system. Default is 4326.

at

Optional numeric vector; breakpoints used for visualization.

layer_name

Optional layer name passed to mapview.

...

Additional arguments passed to mapview::mapview().

basemaps

Character vector of basemap providers. The first provider is shown initially; the others are available in the layer control. Defaults to "Esri.WorldGrayCanvas", "OpenStreetMap", and "Esri.WorldImagery". Passed to mapview::mapview().

Value

An interactive mapview object.

Examples

if (FALSE) { # \dontrun{
map_points(Groningen, value = "amount")
map_points(Groningen, value = "amount", basemaps = "OpenStreetMap")
} # }
